R.- wEsToN SACK HOLDER Filed Aug. 29, 1939 fil' Patented Mar. 18, 1941 UNITED STATES PATENT orties SACK HOLDER Roy Weston, Toppenish, Wash. Application August 29, 1939, seriainazeasss 2 Claims. (c1. 24a- 97) This invention relates to improvements in. sack holders.

Its underlying purpose is to provide a holder which will hold a sack firmly during filling, but which will also release the sack easily and quickly when the lling has been accomplished.

These facilities are augmented by that struc tural arrangement of the holder which enables the sack to be jigged or shaken to settle the contents while the margin of the sack is still impaled on the prongs.

Another consideration to which attention has been paid is the portability of the sack holder.

With this premise in mind the objects of the invention are as follows:

First, to provide a sack holder which enables quickly attaching and detaching a sack, respectively when empty and filled, without injury to either the operators hands or clothing by the supporting prongs which are used therein.

Second, to provide a sack holder which has speed of operation as one of its attributes, the supporting prongs being so disposed that the margin of the preparatory to sack is easily emplaced thereon lling, and the sack is as easily in conjunction with the sack holder, providing a convenient support when none other is available, said stand also being foldable for easy transportation.

Other objects and advantages will appear in the following specification, reference being had to the accompanying drawing, in which:

Figure 1 is a perspectiveview of the sack holder, illustrating its application to a supporting stand.

Figure 2 is a cross section taken on the line 2-2 of Fig. 1.

Figure 3 is a horizontal section taken on the line 3-3 of Fig. 2.

Figure 4 is a cross section taken on the line 4-4 of Fig. 2.

Figure 5 is a perspective View of the frame which is only partially shown in Fig. 1.

The invention comprises the sack holder, generally designated I, and the stand, generally designated 2.

These two elements are adapted to be used in combination in many instances when no suitable support is available for the sack holder I alone.

But the latter is so constructed, as is readily seen, thatit can be attached to a support other than the stand. For that reason the sack holder I- is of foremost importance, and its combinationwith the stand 2 of next importance. The sack holder comprises a foundation .3. This is in the nature of a bracket, and it comprises the carrier of a frame 4. The foundation 3 includes a pair of strong hooks 5 which extend up from a bar` 6 that constitutes the back of the bracket. Said bar extends beyond the hooks and is there converted into forwardly extending lugs 'I which provide part of a hinge connection.

This particular relationship of the hooks 5, bar 6, and lugs 'I is not necessarily adhered to always because these' elements are capable of being correlated in other ways without affecting the principle whatsoever. The foregoing hinge connection is' completed by a bolt 8 which goes through the l'ugs 1. Said bolt is headed so as to retain it in the lugs. One of the heads may comprise a nut 9 that is screwed on in the ordinary way.

The-foregoing frame 4 comprises the telescopic sides Il). which a rod l2 is slidable. The pipes Il and rods I2 are herein known as vtelescopic frame members, the one being the outer member and the other the inner member. 'I'he pipes Il are screwed into the laterals I3 of Ts I4. These, in turn, are screwed onto the ends of a pipe I5 which constitutes the bridge-piece for the back of the frame 4. The corresponding bridge piece for the front of the frame comprises a yoke IS which joins the rods I2.

Actually the rods I2 and yoke I6 comprise a single metallic piece. It is in the form of a U, and the yoke I6 is curved upwardly, as shown, to provide a convenient push bar. It also provides a pull bar depending on how the inner frame is actuated in reference to a sack.

Said inner frame has a set of prongs Il. These are integral with the rods I2 and they project forwardly therefrom on the undersides. Corresponding but rearwardly directed sets of prongs I8 are alxed to the Ts I4 or to equivalent parts of the outer frame. Sleeves I9 depend from the undersides of the frame members II. They are in line with the prongs I'I so that the latter can be retreated into the sleeves by pushing in on the yoke I6, thus to remove the support of said prongs from that portion of a bag margin im- Each of these consists of a pipe II in paled thereon. This releases the front of the sack.

Chains 20, cr equivalent yieldable connections, are attached to the hooks 5 and to the frame 5 members Il, so as to limit the swinging of the frame 4 to a substantially horizontal position. These chains obviously yield when the frame 4 is lifted by swinging it upon its hinges 1, 8, and when that is done the remainder of the sack margin slips off of the prongs I8 so that the sack is deposited on the ground or some flat surface.

The hooks 5 can be mounted on any appropriate support which is strong enough to carry the sack holder and the ultimately loaded sack. Such a support might comprise the side of a bin or something of a similar nature. In many cases, however, a suitable support is not available. For that reason the stand 2 is supplied to complete the combination. It consists of a head board- 2I tance between a pair of upright angle bars 22. These are appropriately cross-braced'at 23, and they are hingedly affixed at 24 to a base 25 which rests on the ground. The angle bars 22 and base 25 are interconnected by bars 26 which are pivoted to the base at 21 and removably attached to the bars 22 at 28. Bars 26 have openings 26a to receive stud bolts 28 for holding stand 2 at an angle to the vertical.

The latter attachment consists of bolts and wing nuts. Upon desiring to collapse the supporting stand, the wing nuts 28` are unscrewed from their bolts, whereupon the brace bars 26 are removed from the bolts, and the base and uprights are folded together so as to bring the stand parts as closely together as possible.

The operation of the sackholder is readily understood. Regardless of where said holder is mounted, the frame 4 will be let down to the 40 horizontal position in readiness for the emplacement of a sack. The margin of the sack is irst impaled upon the back prongs I8. The operator then pulls forward on the sides of the margin in readiness to impale the front of it upon the 45 prongs I 7. These can either be brought to the exposed position shown by pulling forward on the yoke I6, or the latter can be left in a retracted position with the prongs I'I concealed in the sleeves I 9.

which is strongly attached to and spans the dis- Then by drawing the front part of the sack margin over the sleeves I9, said margin will be ready for emplacement by the prongs II when the yoke I6 is pulled forwardly. 'I'he margin of the sack is thus held open and the material can be loaded in with no interference whatsoever from the sack holder. 'I'he contents can be shaken from time to time merely by taking hold of the yoke I6 and swinging the frame 4 up and down a few times on its hinge. f I

Upon desiring to release the4 sack, yoke I6 is rst pushed in. This retreats the prongs II Within the sleeves I9. The margin of the sack is lthus dropped at the front. The yoke I6 is then lifted causing a swinging of the frame 4 upon its hinges, and when the frame is swung suiciently high (Fig. 2) the back of the sack will slip off of the prongs I8 and then be ready for transportation.

I claim:

1. A sack holder comprising a supporting bracket, a frame consisting of a bridge piece turnably mounted on the bracket, tubular arms se-v causing the sleeves to automatically push the sack n pendent from the arm, into which the prong isV adapted to move back rst upon said sliding, thereby to obstruct the sack vportion and push it oif the point of the prong.
